N-substituted pseudo-aminosugars, their production and use

Abstract

A compound of the formula: ##STR1## wherein A is a chain hydrocarbon group having 1 to 10 carbon atoms optionally substituted by hydroxyl, phenoxy, thienyl, furyl, pyridyl, cyclohexyl or an optionally substituted phenyl group, or a cyclic hydrocarbon group having 3 to 7 carbon atoms optionally substituted by hydroxyl, B is hydrogen or hydroxyl, and their production and use. These compounds exhibit excellent inhibitory activity against α-glucoside hydrolase, thus are useful for hyperglycemic symptoms and various disorders caused by hyperglycemia.

What is claimed is: 
     
       1. A compound of the formula ##STR35## wherein A is a cyclic hydrocarbon group having 3 to 7 carbon atoms which may be substituted by hydroxy and B is hydrogen or hydroxyl. 
     
     
       2. A compound as claimed in claim 1, namely N-(2-hydroxycyclohexyl)validamine. 
     
     
       3. A compound as claimed in claim 1, namely N-[(1R,2R)-2-hydroxycyclohexyl]valiolamine. 
     
     
       4. A compound as claimed in claim 1, namely N-(2-hydroxycyclohexyl)valiolamine.
